Importance & Motivation National emission reduction targets [USA] Emission in 2020 reduce by 14-17% compared with 2005 [ EU ] Emission in 2020 reduce by 20-30% compared with 1990 [RUSS] Emission in 2020 reduce by 15-25% compared with 1990 [JP] Emission in 2020 reduce by 25% compared with 1990 [AUS] Emission in 2020 reduce by 25% compared with 2000 China s Position Chinese Premier Wen Jiabao promises: the CO 2 emissions per unit GDP in 2020 will reduce 40%- 45% compared with 2005. In August 2010, The National Development and Reform Commission(NDRC) launched the pilot program on national low-carbon provinces and cities in Beijing, which include 5 provinces and 8 cities.
Importance & Motivation -Why Guangzhou? Location Guangzhou is the capital of Guangdong province in the southern part of China. It is a port on the Pearl River, navigable to the South China Sea, and is located about 120km (75miles) northwest of Hong Kong.

Importance & Motivation -Why Guangzhou? Enhance industrial competitiveness Slow down the rapid growth of energy demand reduce emission to response the climate change Guangdong is one of the five Low-carbon pilot provinces. As the capital of Guangdong, Guangzhou should explore the low-carbon development path actively to play a leader role.
Socio-Economic Assumption in 2030 Quantitative socio-economic assumption in 2030 Population Indicator Set Value(2030) 2030 Tendency Demographic composition Population distribution Average number of person per household Estimates based on The Eleventh Five-Year Plan of Guangzhou National Economy and Social Development 0-14: 8% (14.8% in 2005) 15-64: 80.5% (77.6%) 65 and over: 11.5% (7.6) Urbanization rate is 95% ( 82% in 2005) Urban: 2.6 (3.2 in 2005) Rural: 3 (3.55 in 2005) Growth rate at 1.2% per annum Birth and death rate are declined Urbanization increases Significant decrease in average size of household GDP Growth rate is 6% per annum Guangzhou is on increasing economic growth trajectory and has priorities in meeting the development needs.
Energy demand and GHG emission in 2030 1. Energy demand The total energy demand of Guangzhou is projected to increase about 3 times from 2005 to 2030 BAU. In CM scenario it is reduced about 46% from BAU. In 2030 BAU, the energy system of Guangzhou would rely more on coal and oil, the share of coal would rise to 70%, followed by oil (28%), natural gas(1%), renewable and hydropower less than 1%. In CM scenario, the share of renewable energy would increase significantly. -46% Final energy demand by sector Primary energy demand
Energy demand and GHG emission in 2030 GHG emission (MtCO 2 ) 2. GHG emissions In CM scenario, the total CO 2 emission will reduce to 143 million t-co 2, it is a significantly decrease from BAU. CO 2 emission from industry will be still maintain the largest share of total both in BAU and CM. Reducing the investment for industry sector, improving efficiency of energy, and actively developing the tertiary industry are the direction of development in Guangzhou in the future. 450 400 350 300 250 200 150 100 50 0 Passenger transport Freight transport Industry Commercial Residential 2005 2030BAU 2030CM CO 2 emissions by sector
Emission reduction Action 1: Convenient Transport Modal shift Efficiency improvement Passenger transport: the share of private vehicles reduce 25%, bus and train increase 20%, bicycle and walk increase 5%; Energy efficiency improve 50%. Freight transport: the share of vehicles reduce 25% and 30% in domestic and cross border respectively, train increase 26%, ship increase 4%; Energy efficiency improve 50%. 100% 2% 80% 60% 40% 20% 0% Efficiency improvement Modal shift CO2 emission reduction by action 1
Action 2: Green Building Efficiency improvement Distributed renewable energy Efficiency improvement: shift to equipment with outstanding energy efficiency, such as: energy-efficient appliances, office equipment, lighting, elevator and so on. Distributed renewable energy: subsidy to introduce natural energy system (solar and wind energy); Low interest loan in investment to buildings using renewable energy. 22% CO 2 emission reduction by action 2
Action 3: Decarbonation of Industry 30% It comprises two aspects: energy efficiency improvement and industrial restructuring. Energy efficiency improvement: improve equipment utilization efficiency, accelerate the transformation of large-scale equipment, energy management and recycling of surplus energy. Industrial restructuring: eliminate backward production capacity, expand industrial scale, and investment shift from energy-intensive industries to the tertiary industry.
Action 4: Fuel Switch Industry sector has the largest share of CO 2 emission reduction, following by building and transport sectors. 7% A shift from high carbon intensity fuel to lower ones; encourage the utilization of new and renewable energy. Industry nature gas and electricity increase 5% and 10% to replace coal Building nature gas and electricity increase 10% and 20% to replace oil Transport products nature gas and biofuel increase 20% to replace gasoline and diesel
Action 5: Low carbon Electricity 39% The main measures are power generation efficiency improvement and fuel switch Power generation efficiency improvement: energy efficiency improvement, expand power generation capacity, reduce transmission loss Fuel switch: increase the use of renewable energies, develop nuclear power plant, and to promote the creation of energy from wastes.
